Project: HiCAD Steel Engineering
In this example a planar infill, consisting of a plate, 2 welded holders on the right ans 2 on the left are to be created as railing variants.
Planar infills require at least the variables i_l and i_h.
In this example, only the these two mandatory variables will be of relevance, i.e. this component can only be used for planar infills (an example for railings with rise can be found in the Example variants).
Step 1: Create and parameterize the plate
The steel plate used in our example must be derived from a sketch.
Variable | for | Start value |
---|---|---|
i_h | Distance between floor and handrail | 700 |
i_l | Distance between 2 posts | 800 |
distance | Width of holders | 144 |
h_top | Distance to handrail | 100 |
h_bottom | Distance to floor | 100 |
h_holder |
Distance of holder from upper and lower edge of plate |
100 |
For the width and height of the plate this means:
First, fix the isolated point (1) (Sketch > HCM > Fix geometry). This point represents the origin. Then, assign the variable to the sketch by defining the corresponding HCM dimensional constraints (Sketch > HCM > Smart dimensioning):
Dimensional constraint for |
Variable |
Start value |
---|---|---|
Distance of left edge of sketch to point (1) |
distance |
144 |
Distance of lower plate of sketch to point (1) |
h_bottom |
100 |
Width of sketch |
i_l - (2*distance) |
800 for i_l |
Height of sketch |
i_h - h_bottom- h_top |
700 for i_h 100 for h_oben |
Step 2: Assembly and Fitting CS
Not all assembly automatically have a Feature log. If you assign a Fitting CS to these assemblies, no corresponding Feature entry will be created. However, such an entry is mandatory for the variants. Therefore, assign a body creation feature to the assembly. To do this, right-click in the Feature window of the assembly and choose the corresponding function.
Furthermore, the function must use external references. To do this, right-click into the Feature log again and activate the External references in processings: ... option.
The variables pl[1] and pl[2] will be assigned to the feature of the plate:
The Fitting CS will then be entered into the Feature log of the assembly (the points coincide with the isolated points you used when you created the sketch).
Step 3: Insert holders and parameterize:
You are now done assigning all required variables and HCM constraints to the assembly.
Step 4: Save assembly as variant
In the HiCAD folder Kataloge\Werksnormen\Stahlbau\Gelaender\EbeneFuellung , the following new files have been added:
The variant is now available in the Railing Configurator as an infill.
